how far off was the time/date? since this happened after the move, this hints that the battery on the system board is dead and needs replaced. this means potentially every time the system is powered off, the time will be reset along with any customized bios settings... i suggest submitting a ticket to your hosting provider to have them replace the battery as soon as possible...

1. Register a new app at http://dev.twitter.com/apps/new
2. Fill in tokens and server info in twitter.php
3. Upload title.txt, twitter.php, EpiCurl.php, EpiOAuth.php, and EpiTwitter.php to your webserver IN THE SAME FOLDER!
4. Make sure that title.txt is writable (chmod 777)
5. Visit twitter.php in your browser or setup a cron job (explained earlier in this thread)
